The specimen certificate SPECIMEN

Basil & Rye Bakery, LLC — sample · Trial balance as of June 30, 2026 · reviewer of record A. Reviewer (SPECIMEN) · issued Jul 6, 2026 15:33 UTC

Valid
This SPECIMEN passes the same checks a real certificate does. It is built from SAMPLE data for a fictional client and is not a record of any business.
  • Passes: Body hash recomputed from the body and equal to the recorded hashrecomputed ec4e 58bd c217 57a1 c3ac e5ca 050b 1cda 675e d48b 74cb 0083 0d0c 3f63 ef62 6f2e
  • Passes: Evidence chain verifies record by record from genesis, including every certificate anchor
  • Passes: Issuance record in the chain names this certificate and this hash
  • Not timestamped — A SPECIMEN is not timestamped. That is not a failure: issuance never waits on the timestamp authority.

What this proves

That these inputs — identified by SHA-256 on the certificate — produced this result on this date, that a named reviewer approved the resolutions shown, and that the record has not changed since, as far as the hash, the evidence chain and the timestamp can show. It is tamper-evident.

What it does not

It is not an examination of the books and not an opinion on the financial statements; it does not say they are free of error. An operator with database access could rewrite a record and its chain — which is why the RFC 3161 timestamp anchors the hash in time with an outside authority that a rewrite cannot reproduce. Ledger access was read-only throughout.

Check it yourself: canonical JSON of the body (sorted keys, no whitespace) → SHA-256 → compare with the hash above; then openssl ts -verify -digest <body sha256> -in token.tsr -CAfile digicert-tsa.pem on the timestamp token the certificate’s holder can give you. The verification as JSON.

Independent tie-out · Trial balance · Read-only

On July 6, 2026, BookSyncHQ compared the trial balance of Basil & Rye Bakery, LLC — sample as of June 30, 2026 in the built-in sample QuickBooks Desktop file with the trial balance in the built-in sample QuickBooks Online file — both identified by SHA-256 in Schedule A — account by account, in integer cents, exact equality only, and found the two Balanced: 22 of 22 accounts agreeing to the cent, every difference 0.00, and each side self-balancing at 275,000.78. Run 1 found three breaks: two corrected in the books, one accepted with a written reason and tied on the re-run (Schedule C).

What this certifies. That the inputs identified by SHA-256 in Schedule A produced the result stated at the moment recorded, after the resolutions in Schedule C approved by the reviewer named, and that this record has not changed since — as far as its hash, the client’s evidence chain and a timestamp can show. It is tamper-evident. What it does not. It is not an opinion on the financial statements; it does not examine the transactions the ledgers agree on or say the books are free of error. An operator with database access could rewrite a record and its chain, which is why an RFC 3161 timestamp anchors the hash in time with an outside authority. Ledger access was read-only throughout.
